Abstract: T-2DPCA, a novel approach considering the third-order tensors as linear operators on the space of oriented matrices, benefits from treating a 2D image as an inherently integrated object, has been proposed recently and showed better performance than traditional matrix PCA in image analysis and recognition. In T-2DPCA, a reconstructing tubal coefficient is obtained from the defined tensor product, called T-product, of a 2D image and a 2D basis element. In this study, by assuming that an eigenvector of the covariance tensor of the 2D training images is the tensor linear combination, called T-linear combination, of the training images, the T-2DPCA is improved to a new version with better performance. The improved method is further extended to a nonlinear version by using the general kernel trick in machine learning field, but with a new inner product called inside product defined with the T-product in the third-order tensor spaces, and simultaneously the general inner product defended in vector spaces. The effectiveness of the proposed algorithms is tested by face recognition experiment results.

Abstract: The paper focuses on the poultry meat production efficiency analysis methods. In the poultry meat production procedure, the randomness is strong due to the various complex factors in the poultry meat production which will reduce the production efficiency. In order to avoid the defects of the traditional algorithms, the paper proposes the poultry meat production efficiency analysis method based on RBF neural network algorithm. The effect factors in the poultry meat production will be sifted as the basic data for production efficiency analysis. The RBF neural network model is built and the output results are used to analyze the poultry meat production efficiency with intelligent devices. The experiment results illustrate the improved algorithm can increase the poultry meat production efficiency.

Abstract: Aiming at making the simulation of human visual attention behavior more truly in computer, starting from analyzing operator’s cognitive model, a gesture tracking algorithm is put forward based on the distribution model of visual attention. To begin with, analyzing the change of the operator human eye sight, a visual attention model was built. Secondly, the basic characteristics of visual attention model were studied. Finally, the three Gauss formula is used to describe the model. Experimental results show that the algorithm can effectively improve the speed and tracking accuracy of gesture interaction.

Abstract: In today's society rapid development of science and technology, the computer figure image design can be widely used in various industries. In the film and television, advertising, exhibition, art, electronic play in areas such as lack of necessary computer graphics design. With the development of computer information technology, the design of the graphics technology will progress. On the technology no longer content with a simple graphics rendering, more note focus on visual sense of the data, enhance the figure shape the image of beauty and expression. This paper mainly discusses the computer graphics design and visual communication design in today's society rapid development of science and technology, computer graphics design has also been extensively applied to various industries. In the film and television, advertising, exhibition, art, video games, and other fields are short of necessary computer graphics design. With the development of information technology, computing machine graphics design technology progress. Current technology is no longer satisfied with the image of a simple now, pay more attention to the visual sensation of biography and enhance the figure shape the image of aesthetic feeling and expression. This paper mainly discusses the computer graphics design and research of visual communication design.

Abstract: Resource discovery is the key of network resource management, which includes multiple aspects, such as resource description, resource organization, and resource discovery and resource selection. For a long time, communication network resourcehas been lack of unified and standardized description, causing users difficult to precisely find related resources in demand. This paper presents a distributed resource query methods based on management domain, including distributed resource query architecture, the basic process of resource discovery, update method,query methods and so on. The method of network resources makes use of collaborative queries to realize network resource discovery according to need.

Abstract: To meet the practical demands of mobile Ad Hoc network on quality of service, we proposed an improved wireless on-demand routing protocol on the basis of traditional AODV. We integrate multi-path routing into route discovery process and arrange data originated from source to be transmitted over several different paths concurrently, and defined the path level to evaluate the path’s transmission ability based on its available bandwidth. Numerical simulation results demonstrate the proposed routing protocol outperforms AODV in end-to-end delay, packet delivery rate and network lifetime.

Abstract: The existing web frameworks focused on the encapsulation of bottom technical, could not commendably support large granularity and lack corresponding mechanism in terms of reusability and maneuverability.In the current study, a new web application framework NSSH was developed from by SSH frameworks.The new framework with characteristic of large granularity and high level reusability separated and encapsulated the presentation layer,business layer and data persistence layer,simplified the development of Web application,improved the usability, reliability and extendibility.Based on the design of NSSH,the application development platform was put forward which make the web application developer free from heavy low level code programming works and be able to pay more attention to the description of business logic and definition of user interface.The practice had proved that NSSH was applicable for developing large-scale web application by enhancing the efficiency of those complex systems.

Abstract: This research points out the negative effects given by malware attacks first, then put forward that the botnet is the major threaten to the network security especially the new hybrid P2P based botnet. The research mainly focuses on introducing the mechanism of this new type botnet and proposes the defense method in order to construct a safe network platform.

Abstract: Information security is a great challenge for organizations in our modern information world. Existing security facilities like Firewalls, Intrusion Detection Systems and Antivirus are not enough to guarantee the security of information. File is an important carrier of information, which is the intent of quite a number of attackers. In this paper, we extend the FPD-based approach for detecting abnormal file access behaviors. We propose 3 approaches to calculate FPD values in the case of lacking training data, and we apply a k-means based unsupervised approach to distinguish between normal processes and abnormal ones. Experiment demonstrate that our unsupervised approach is still effective compared to the supervised case with training data.

Abstract: With the development of ASP.NET platform, ASP.NET architecture system increasingly mature and increasingly wide range of applications, ADO.NET technology to become the key technology of this system, database access, data processing and application development. This paper mainly studies the database access of ADO.NET. First introduced ASP.NET technology and several ways of ASP access to the database, which shows the advantages of ADO database access; secondly expounded the principle of ASP.NET access to the database, ASP.NET to access database through the ADO of the internal components; then introduces the main object types of ADO.NET database access required, ADO.NET is an improved version of ADO, including Command, Connection, DataAdapter, DataSet and DataReader, and so on. And describes their respective functions; finally, introduces the basic process of ADO.NET to access the database. And implementation of SQL Server database connection.
